Discussion on Several Problems about Stress Test on the Spot for a Long-Span Prestressed Concrete Continuous Rigid Frame Bridge

Bin Du

Abstract

During construction of a long span prestressed concrete continuous rigid frame bridge,a set of strain transducers are installed in its key sections for measuring the structural strains,With the help of error analysis,the stress test results of a long span prestressed concrete continuous rigid frame bridge are approximate to the actual structural stresses.It is the basis that can be used to analyze the structural stresses,modify the structural design and estimate the engineering quality.
